Abstract
The heterocyclic ring in the title compound, C10H7F3O3, has a half-boat conformation with the hydroxy-bearing C atom lying 0.595 (3) angstrom out of the plane of the five remaining atoms (r.m.s. deviation = 0.022 degrees) in the direction of the hydroxy O atom. Linear supramolecular chains along the a axis, sustained by O-H center dot center dot center dot O hydrogen bonds between the hydroxy H and ketone O atoms, feature in the crystal packing. These chains are connected into a three-dimensional architecture by CH center dot center dot center dot O and C-H center dot center dot center dot F contacts.
